Abstract: Objective To explore the transverse characteristics of basal bone and maxillary mandibular first molars in adult patients with skeletal class Ⅱ malocclusion, and to analyze the correlation between the characteristics and vertical facial types. Methods A total of 70 adult patients(35 males and 35 females, age 18-47 years, mean 25.26 years)with skeletal class Ⅱ malocclusion(∠ANB ≥ 5 °)were divided into three groups according to the mandibular plane angle(∠FH-MP): hypodivergent group(∠FH-MP<22°, n=23), normodivergent group(∠FH-MP=22°-28°, n=24)and hyperdivergent group(∠FH-MP>28°, n=23). Data were scanned with cone beam computed tomography(CBCT). The maxillomandibular basal bone width, intermolar widths, maxillomandibular intermolar width between centers of resistance, molar inclination, and thickness of alveolar bone were measured with Mimics21.0. Relevant factors were assessed with One-way ANOVA, LSD method and Pearson correlation analysis. Results The maxillomandibular basal bone width and intermolar width between centers of resistance of the upper first molars were shorter in the hyperdivergent group than in the other two groups(P<0.05). The mandibular plane angle was negatively correlated with the maxillary basal bone width and the intermolar width between centers of resistance of the upper first molars(r=0.279, -0.468). The width difference between centers of resistance of the upper and lower first molars in hyperdivergent group was smaller than that in hypodivergent group(P<0.05). The buccal inclination of upper first molar and the lingual inclination of lower first molar in hyperdivergent group were higher than those in hypodivergent group(P<0.05). The mandibular plane angle was positively correlated with the buccal-lingual inclination of the upper first molar(r=0.422), and negatively correlated with the buccal-lingual inclination of the lower first molar(r=-0.272). The buccolingual width at the alveolar crest of upper first molar at centers of resistance level in hyperdivergent group was lower than that in hypodivergent group(P<0.05), and that of the lower first molar in hyperdivergent group was lower than that in the other two groups(P<0.05). Conclusion Compared with the normodivergent and hypodivergent patients, skeletal class Ⅱ hyperdivergent patients have smaller width of the maxillary base, more buccal inclined upper first molar, more lingual inclined lower first molar, and thinner buccolingual width at the alveolar crest of upper and lower first molar at centers of resistance.
